Predicting The Effective Temperaure of a Glass
arXiv:0912.1120 · doi:10.1103/PhysRevLett.104.125902
Abstract
We explain the findings by Di Leonardo et al. [Phys. Rev. Lett. 84, 6054 (2000)] that the effective temperature of a Lennard-Jones glass depends only on the final value of the density in the volume and/or temperature jump that produces the glass phase. This is not only a property of the Lennard-Jones liquid, but a feature of all strongly correlating liquids. For such liquids data from a single quench simulation provides enough information to predict the effective temperature of any glass produced by jumping from an equilibrium state. This prediction is validated by simulations of the Kob-Andersen binary Lennard-Jones liquid and shown not to apply for the non-strongly correlating monatomic Lennard-Jones Gaussian liquid.
